It does effect you.
Ok let AA end all ETOPS flights so that eliminates all widebodies, so AA doesn’t need line mechanics to do the required line maintenance work, can close some heavy maintenance bases, lay-off lots of overhaul employees, and get rid of lots of ramp workers at all US cities since they can eliminate all ETOPS flying and of course that would reduce profits also, so let AA file bankruptcy to cut you’re wages, benefits and jobs. And since their would be no International flying, I can reduce domestic flights and narrowbodies as AA doesn’t need the feed anymore, so I can lay-off more ramp and mechanics. AA won’t be buying any four engine airplanes to replace ETOPS operations. So yes those foreign based AA employees do effect the bottom line.
You don’t see the big picture.
